Abstract
The water-conserving liquid ring vacuum pump system receives the output from a water ring vacuum pump, removes the air and contaminants from the water, and returns the clean water to the make-up water port on the pump, thereby saving most of the water that would normally be discarded. Friction in the pump also heats the water, so the system is designed to cool the water as well.
